Hi,

I am in the process of finishing the setup of my site builder, but there are a few issues that I can't figure out.

1) I can't upload any pictures, I have tried uploading small size pictures but event those won't upload, its giving me a "fail" error

2) Thumbnails are not being generated in site previews, blocks, and templates

3) Is not sending welcome emails, or password reset emails, it's giving me an error that something went wrong.

I have tried to give folders permission 755 and files permission 644, but it's still not working.

Thank you
